People are reporting that logging into your characters from a Windows installation and then copying your cache folder from Windows to Linux fixes the issue.
Simple copying didn’t fix it for me, but deleting Cache folder in Wine installation first did.
This error occurs on my client when:
- always in the moment I log in on 1 char
- from time to time on the others when I either open the Map (always) or inspect people (always) or just randomly (sometimes)
It’s getting to a point where it is unplayable 
Really sad, I still miss the mage tower challenge with the feral druid and that char can’t login no matter where the game masters port me.
Even a complete reinstallation didn’t work.
Hi yes I’m having this error after downloading the pre-patch for BFA. I delete my cache folder, reset my wtf,Interface folders the problem still persists. On some toons I got a good 5 minutes then boom streaming error. I’m on Ragnaros -EU
What do you do when you don’t have a windows installation nor want to have one?? 
I answered my own question. Yay for internets
it fixed the streaming error issue for me. Hope this helps others too.

hello yes i am having this probrom too error 51900322 ,i see people using addons which i think blizzard are trying to break successfully it seems ,and now breaking it for ubuntu users and linux users alike
Download the Windows WOW cache from the link and replace it. Don’t merge or anything like that overwrite it. and you’re good to go .
I’m getting this issue now too after reinstalling WoW.
No addons.
Replacing the cache doesn’t help either. Me sad
EDIT: Cache that fixed it for me: https://web.tresorit.com/l#mD9ZiPy9-NmivJiT7OIl1Q
Hm, I’m again having this issue with the BFA release, and I have found no way of resolving it.
I have verified the cache db fix works. If you can, run through the heart once on a Windows machine and then copy the Cache directory from Windows back to your Lutris install.
Hi all,
I have the same problem, but it occurs when opening chests(but the content then goes to my mailbox) and when opening the profession window.
When I had the problem a few months ago, the game disconnected right on login onto one specific character, nut all others were ok.
I copied the Wow installment from my girlfriends PC which also runs Linux and it worked again.
So I assume there is no need for a Windows cache, but somewhere in the installment is an issue which causes that behavior…
I also am having the streaming error crashes in BFA. I dont have anything else to contribute other than I have tried various settings to no avail.
Anybody got any BFA streaming error advise?
My WoW client had been crashing with this error since it was installed - after the release of BFA - in certain circumstances including loading the PvP and Appearance panes. Since yesterdays patch the streaming error now occurs on every attempt to login as a character.
I have disabled all of my addons with no change.
The solution is still above.
Hi Dox,
Not sure if youre familiar but there has been a new WoW expansion. The old cache file doesnt seem to work…

Open an issue, ask for fresh copy of Windows cache?
Done and done. Thanks
You can try this, perhaps it works.
Ok so thank you Dox,
Some combination of applying this fix (the reddit one above) + restoring the cache with that 2 month old file + using staging 3.14, has allowed me to login to my characters and I am getting 90+ FPS btw.
I wish I could reproduce the problem and figure out just exactly which fix was the reason it is now working…
Anyway,
Thanks
-David
EDIT:
Woke up today after installing steam yesterday and couldnt get past hitting play in WoW (it gave a black screen of sorts). However, I disabled streaming via the battle.net app as per the documentation on github and was then able to log in correctly. Hope this helps someone.
